SNOW-PLOW.

SPECIFICATION formingpart of Letters Patent No. 768,607, dated August30, 19.04. I Application ilel April 4, 1904. Serial No. 201,607. (Nomodel.)

T o all whom, it may concern:

Be it known that I, ARTHUR LABELLE, a subject of the King ofGreat-Britain, residing in the city and district of Montreal, in theProvince of Quebec, Canada, have invented certain new and usefulImprovements in Snow- Plows`; and I do hereby declare that the fol- A'lOlowing is av full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same.

' This invention relates to new and useful improvements in Asnow-plowsadapted for use upon railroads for the-purpose of clearing .snow fromthe tracks thereof; and it consists in certain features of novelty inthe construction and operation of theparts thereof, all as hereinaftermore fully described, and specifically set forth in the claims.

The object of the invention is to produce a snow-plow of the characterdescribed which will be so constructed as to cut its way through anembankment of snow and present only such portion of the snow tothe wedgeconstituting the plow proper as will be necessary for clearing a giventrack, thus avoiding the packing of snow, which has been found to be anobstacle in the Way of the successful operation of snow-plows heretoforesuggested.

Referring to the drawings, in which similar numerals of referenceindicatecorresponding parts in all the views, Figure l is a sideelevational view, partly broken away for the purpose of better showingdetails of construction. Fig. 2 is a plan view of the snowplow with theroof of the cabin thereof re manipulating the plow.

Referring to the drawings, l is a rear truck provided with supportingwheels 2 and a transverse bolster 3, adapted to support the platform 4,upon which platform is mounted the plow, which for convenience ishereinafter referred to as a wedge.7 At the forward end of the platform4 are supporting-wheels 5, which are of less diameter than the wheelstors of the plow for the purpose of shelterj ing such operators fromiiying material operated upon in the process of cutting through thesnow.

Extending longitudinally of the car comprising the truck 1, bolster 3,platform 4, and supporting means is a sheathing 8, which extends fromthe truck-platform down to a point just slightly. removed from the saidtrack-rails 6, so as toprevent the passage of snow laterally under thetruck, which snow might have a tendency t'o dislodge the car from thetrack. Projecting slightly beyond the forward end 9 of the car andextending thence upwardly of the inclined iioor 10 are side walls 11,which are provided with vertical braces 12, transverse braces 13, andwith the doors 14, connected to the side walls by means of thestrap-hinges 15, as shown in the drawings, or by any other convenientsecuring means. -Projecting laterally from the walls 11, as best shownin Fig. 2, are socketed members 16, which are adapted to receivevertically-reciprocatory rods or bolts connected with the doors 14 forthe purpose of securing the doors ina forward position, as shown by thedotted lines in Fig. 2, this position being desirable when the point 17of the plow isswung toward the left o'r lower side, as shownv in thedrawings. It will be noted that the door shown dotted in Fig. 2 is atthe upper side or right-hand side as the apparatus advances; but whenthe plow is turned to that position it is preferred that the oppositedoor shall be open and the door at the righthand side shall be closed.

Suitably supported upon the platform 4 is a wedge shaped structurecomprising the wings 18,.which converge toward the point 17. as bestshown in Fig. 2.' The point 17 may comprise a casting, if desired, to.which is secured the said wings 18, the said casting affording a betterresisting medium for the SiO IOO

impact of the snow and ice which will be projected thereagainst in thepractical use of the apparatus. Connected with the inclined floor 10 ateach side of said Hoor are sockets 19, into which sockets 19 pinspassing through the lugs 2O on the point 17 may be projected for thepurpose of securing the wedge in a position wherein the point will beheld at either side of the said inclined floor 10. Between the wings 18,at the forward ends thereof and just behind the point 17, is asupporting-roller 21, upon which the said wedge will ride in its lateralmovement. Extending transversely between the wings 18 within the lowerportion thereof are brace-rods 22, which by means of angular extensions23 are connected with said wings and which extend from thence to theplate 24, (shown in Figs. 3 and 4,) while a second transverse brace 25,also connected with said wings, extends to said plate 24, the braces 22and 25 being connected with said plate at opposite sides of the eentralopening in said plate 24, upon which it turns. Below the plate 24 is asecond plate 26, between which and said plate 24 frictionredueing balls27 are provided, and the plate 24 is freely rotatable upon said plate 26when desired. Connected with the upper portion of the said wings 18 area plurality of bracerods 28 and 28, which are connected to a yoke 29 orwhich terminate in a yoke embracing the upper end of the fixed standard30.

Vithin the cabin 7 is provided an ordinary brake-staff 31, supportedwithin the bracket 32 and by means of the base-plate 33 between theflooring 101 and the superposed iiooring 34 within said housing. Uponthe said brakestaff 31 is a small pinion 35, which meshes with a gear 36upon the shaft 37, suitably supported between the flooring 10'1 and thesuperposed flooring 34, while on said shaft 37 is a sprocket 38, andengaging with said sprocket is a chain 39, which extends thence to thehangers 40, connected to the inner faces of the said wings 18. Anordinary hand-wheel, as 41, on the brake-staff 31 is adapted forrotating said brake-staff, pinion 35, gear 36, and actuating the chain39 through the sprocket 38, and thereby swinging the wedge upon thepivot-plates 24 and 26. (Shown in Figs. 3 and 4.) rlhe standard 31, aswill be noted, is of an increased diameter at its lower portion and isfixed in position by means of the plate 42, which is connected with theliooring 10 by means of bolts 43 projected through the timbers thereof.As the wedge must necessarily rock to some extent in its movement fromthe central point 44 (shown in Fig. 2) to the extreme sides of the car,owing to the inclination of the flooring 10, it is necessary that theplates 24 and 26 be so formed as to compensate for such rocking, and forthis reason the openingI 45 in the plates 24 and 26 is larger at the topthan at the bottom, and as the bracerods 22 and 25 are connected atopposite sides of the plate 24 at opposite sides of the pivotalopening45 itis evident that more or less rocking of the members 24 and26 will result lrom the shifting of the wedge. This is compensated forby means of the plate 46, the upper face of which is curvedapproximately in an are of a circle struck from the yoke 29 at the upperend of said standard 30, the said plato 46 being a part of the plate 42or connected therewith in such manner as to be lixed against movementthereon. Upon th\l advance lace ofthe cabin 7 are provided a pluralityol loops or eyes 48 at different distances from the sides thereof, andthe hooks 49 are adapted to be connected with the lugs 50 upon the wings18 and engage with said loops 48, or, il (clesired, anumber of hooks maybe connected with said loops adapted to engage with eyelets ou thewings.

For the purpose of facilitating the lateral shifting of the wedge and toassist in supporting the rear thereof friction-rollers 5l are provided,one upon each inner side of the wings 18, as best shown in Fig. 3, thesaid rollers assisting in supporting the structure oi' said wedge.

The operation of my improved apparatus is as follows: An engineerothersuitable means being connected with the structure hereiubeforedescribed it is propelled over the tracks 6 and the advance end thereofforced into the snow, which is cut by means of the said walls 11, sothat only such portion thereof as is necessary to permit the passage oftrains will be disturbed, a single track being' cleared only at onetime. In driving the apparatus lorward snow will ride up the inclinediioor it), and if it is a single track the point 1T of the wedge may besupported centrally of the car; but if there is a track either at theright or left of the track on which the apparatus is being propelled thewedge will be turned by means of the hand-wheel 41 and its appurtenantconnections to such position that the snow will impinge only one face ofsaid wedge and be driven either to the right or 'lOO left, as may bedesired, thereby cutting', lilting up, and throwing to one side or toboth sides of the track the snow which it ls desired to remove withoutin any manner disturbing the surrounding bed of snow. As it has beenfound in practice that the snow becomes densely packed and has beenalmost impossible to remove in some instances, the cutting andseparation from the main bed ol that portion which it is desired toremove is considered of great advantage, wherefore the cutting edges 52of the side walls .Il are found to be of great utility, these cuttingedges extending beyond the cara sullicient distance for practical use.

While l have shown in the accompanying drawings the preferred form of myinvention, it will be understood that l do not limit myself to theprecise form shown, l'or many of the detailsmay be changed in form orposition'w'ithout affecting the operativeness o r utilityof `myinvention, and I therefore reserve the right to make all suchmodifications as are included within the scope of the following claimsor of mechanical equivalents to the structures set forth.
